The order in which effects are added to a group affects the final visual representation of the content that the effects are applied to. The effects are chained so that the visual of the first effect is used as the source of the second. This logic is followed through all subsequent effects within the effect group. The following image shows the effect that a DropShadowBitmapEffect and a OuterGlowBitmapEffect have when added to a Button. The first button has the drop shadow applied first and the outer glow applied last. In the second button, the order is reversed.

Multiple visual effects can be applied to a single visible object using the BitmapEffectGroup. The following example shows how to apply a BlurBitmapEffect and a DropShadowBitmapEffect to create a blurry button with a shadow behind it.
